Benchmark Results: SiSoftware Sandra 2011

As we’ve come to expect, Intel’s processors deliver solid integer performance, while the AMD CPUs do well in floating point math. These same results are reflected in both the Arithmetic and Multimedia benchmarks.

The Cryptography test naturally favors the Intel CPUs with AES-NI support. It’s notable that AES hashing bandwidth is actually higher in Sandy Bridge than it was back on Clarkdale. This was something that Intel announced back at IDF 2010, and we see that claim quantified here. Also, bear in mind that the new second-gen Core i3s—just like the first generation—ship with AES-NI disabled. That’s why the Core i3-2100 falls into last place.

Finally, Intel’s dual-channel memory controller appears to be improved, moving up to 1 GB/s more using the exact same modules set to the exact same latencies compared to Lynnfield. The Clarkdale-based Core i5-655K is naturally much slower, since its memory controller is off-die/on-package. Core 2 Quad pulls up the rear, complemented by the last of a dying breed of platforms with chipset-based memory controllers.

Wow Intel owns when it came to converting video, beating out much faster dedicated solutions, which was strange but still awesome.

I don't know how AMD's going to fare but i hope their new architecture will at least compete with these CPU's, because for a few years now AMD has been at least a generation worth of speed behind Intel.

Also Intel's IGP's are finally gaining some ground in the games department.

I really wish this weren't the case fakie--and I'm very sorry it is. We're unfortunately subject to the will of the finance folks and the government, who make it hard to give things away without significant tax ramifications. I know that's of little consolation, but that's the reason

"It’s the value-oriented buyers with processor budgets between $100 and $150 (where AMD offers some of its best deals) who get screwed."

I believe that says it all. Sorry, Intel, your new architecture may be excellent, but unless the i3-2100 series outperforms anything AMD can offer at the same price range WHILE OVERCLOCKED, you will see none of my desktop dollars.

There is some pretty cool stuff going on here. I like the way the article points out the good and the bad. As for me I really am mystified at Intel's decision to only put the higher end graphics in the k-models as most likely anyone buying them will be going for the P67 platform that doesn't even use the integrated graphics. It would have been soooo much better for the HTPC crowd if there were some lower end chips with the better integrated graphics. I guess somehow this is money motivated???

As for overclocking, well it seems a bit odd in the way it is being implemented. But for $216, I can't complain too much about a quad-core with a base clock of 3.3 GHz. Some enthusiasts won't like the limited overclocking features, but others will welcome the simplified approach.

I will be building my brother a new gaming computer for graduation this summer and now I have another viable option to look at. I had planned on going with a P55 + i5 760, but now I will need to consider the P67 + i5 2500K.

I mean this looks like a thorough test but its really not. I wanted to see an I7 1:1 clock performance comparisons. Mainly, 3.4GHz I7-950 vs 3.4GHz I7-2600K. Obviously 3.4 GHz new tech would usually beat a 3.0 current tech in benches. UGH. lame lame lame. Really want to see this comparison instead.

I just bought an i5-760 system on 12/30 from newegg, I guess I wasn't paying attention to when Sandy Bridge would actually be released. It's not here yet, so I could just send the mobo and cpu back when they get here, but I don't see enough justification as a gamer to move to the 2500k. Based on the number of 1.35V 4.7ghz for the 2600k, I would assume that on stock voltage it doesn't get much higher in frequency than my 760 will, and I don't like raising stock voltage.

This is all very nice, but I'll keep my bclk control for now and maybe move up when I get out of college in seven months and the tech is set in stone and dropping in price a little.

In all but the heaviest threaded applications, Sandy Bridge is the fastest chip on the block—and you get the performance at a fairly reasonable price. The Core i7-2600K is tempting at $317 but the Core i5-2500K is absolutely a steal at $216. You're getting nearly $999 worth of performance at roughly a quarter of the cost.

These things are as fast as the i7 980X and in some cases they're even faster!
